pkg: Insufficient privileges

I tried installing acme pkg and it broke my webGUI with PHP ERROR: Type: 64, File: /etc/inc/config.inc, error.
It was suggested to on reddit to issue pkg install -fy pear-Net_IPv6
But I get on the cli pkg: Insufficient privileges as response.
I only have one account and I thought it was an admin account, but seem to miss wheel group uid=2000(linuxlover) gid=65534(nobody) groups=65534(nobody),1999(admins)

What can I do to fix this, I have no access to the GUI to add another account?!
